# Proposed State Implementation Plan Revision Section 110(a)(2)(A)-(M) Clean Air Act Requirements for PM2.5

August 25, 2008

District Department ofthe Environment 51 N Street NE, 6th 

### Floor Washington, DC 20002 George Hawkins, DirectorA State Implementation Plan (SIP) is a plan for each state that identifies how that state will attain and/or maintain the primary and secondary National Ambient Air Quality Standards (NAAQS). The SIP is a complex, fluid document containing regulations, source-specific requirements, nonregulatory items such as plans and inventories, and in some cases additional requirements promulgated bythe U.S. Environmental ProtectionAgency (EPA). The initial SIPs for states were approved byEPA onMay 31, 1972. SIPs canbe revised bythe state with EPA approval as necessary. The federally enforceable SIP for District ofColumbia is compiled in 40 CFRPart 52 Subpart J.

This SIP revision incorporates the requirements ofSection 11O(a)(2)(A)-(M) ofthe Clean Air Act (CAA) which have not been previously addressed. This SIP revision is a compilation ofelements that describe how the District ofColumbia is implementing the PM2.5 NAAQS. The elements ofthis SIP revision, once approved byEPA, will provide a federally enforceable written confirmation ofhow the District ofColumbiawill continue to comply with the Section 110(a)(2)(A)-(M) requirements ofthe CAA.

Legislative authority for the District ofColumbia air qualityprogram is codified in 40 CFRPart 52 Subpart J, which gives the District Department of the Environment the power and duty to implement the provisions ofthe CAA in the District ofColumbia.

Those requirements ofSection 11O(a)(2)(A)-(M) that are already in the approved SIP orrecently submitted SIP revisions relate to: enforceable emission limits and schedules for compliance; monitoring, source testing and emissions reporting; recordkeeping and reporting requirements; and permit fees.

### §11

### O(a)(2)(B) provide for establishment and operation ofappropriate devices, methods, systems, and procedures necessary to monitor, compile, and analyze data on ambient air quality, and upon request, make such data available to the Administrator; The District Department ofthe Environment (DDOE) maintains and operates a multi-stationPM2.5 network to

measure ambient PM2.5 levels within District ofColumbia for comparison to the national ambient air quality standard (NAAQS) as required by 40 CFRPart 58. PM2.5 monitoring is currentlyperformed at various locations throughout the District ofColumbia. All data are measured using U.S. Environmental Protection Agency (EPA) approved methods as either Reference or Equivalent methods; all monitors are subjected to the quality assurance requirements of40 CFR Part 58, Appendix A; and all samplers are located at sites that have
met the minimum requirements ofPart 58, Appendix E. The data are submitted to the EPA's Air Quality System (AQS), in

a timely manner in accordance to the schedule prescribed by the EPA in 40 CFRPart 58 and in accordance with the Section 105 grant commitment (sub-objective 1.1.1).

In order to keep EPAinformed ofchanges to the sampling network, DDOEprovides EPA Region III withprior notification ofanyplanned changes to the network. As needed, details ofthese changes and anticipated approvals of the changes are communicated to EPA. On an annual basis, DDOE sends EPA a summarytable ofall the changes to the network. This summary also provides for a description ofeach change, the reason for each change, and any other information relevant to the change. DDOE submits data to the AQS system in a timely manner, pursuant to the schedule prescribed bythe EPA in40 CFR Part 58. 

### § 11 

### O(a)(2)(E)(i) provide (i) necessary assurances that the state (or, except where the Administrator The District assures EPA that it has adequate authority under the District ofColumbia Air Pollution Control Act of 1984, effective March 15, 1985 (D.C. Law 5-165, D.C. Official Code

### deems inappropriate, the general purpose local government or governments, or a regional agency designated bythe state

or general purpose local governments for such purpose) will have adequate personnel, funding, and authority under
state (and, as appropriate, local) law to carry out such implementation plan (and is not prohibited by anyprovision of federal or state law from carrying out such implementation plan orportion thereof); §8-101 

### etseq.) to carry out its state implementation plan (SIP) obligations with respect to the PM2.5 standards and to revise the SIP as necessary. Theprimary sources offunding for the implementation ofthe PM2.5 requirement are the Section 105 grant funds provided to DDOE, fees collected under the Title V program, and District funding. DDOE believes that the District has and will continue to have adequate funding and personnel to carry out the SIP with respect to PM2.5 requirements.

DDOE does not anticipate the need for additional

resources to carry out the plan for the PM2.5 standard beyond those which have been utilized to date to meet other current programmatic demands.

DDOE is not prohibited by any District law from carrying out any part ofthe implementationplan. § 110(a)(2)(F) require, as maybeprescribed bythe Administrator­

(iii) correlation ofsuch reports bythe
state agency with any emission limitations or standards established pursuant to this Act, which reports shall be available at reasonable times for public inspection; DDOE analyzes emissions data and correlates such data with any applicable emission limitations or standards. Section 105 grants are used to support air quality inspectors, and part of their process is to compare source emissions to emission limitations and standards. All reports are available to the public under the District ofColumbia Freedom ofInformation Act (FOIA) (D.C. Official Code §2-531 

### et seq.)

§ 110(a)(2)(H) provide for revision ofsuchplan­ (i) from time to time as maybe necessary to take account ofrevisions ofsuch national primary or secondary ambient air quality standard or the availability ofimproved or more expeditious methods ofattaining such standard, and The District ofColumbia will review and revise its SIP from time to time as maybe necessary to take account ofrevisions ofsuch primary or secondary NAAQS or the availability of improved or more expeditious methods ofattaining such standard and whenever the Administrator finds on the basis of information available to the Administrator that the plan is substantially inadequate to attain the NAAQS which it implements or to otherwise comply with any additional



### 3(iii) except as provided inparagraph (3)(C), whenever the Administrator finds onthe basis ofinformation available to the Administratorthat the plan is substantially inadequate to attain the national ambient air quality standard which it implements, orto otherwise comply with any additional requirements established under this Act; requirements established under the CAA. When planrevisions

are necessary, the regional planning process through the Metropolitan Washington Air Quality Committee (MWAQC)

orits successors, coordinated with the transportation planning agencies, is used. TheDistrict has adequate authority under the District ofColumbia AirPollution Control Act of 1984, effective March 25, 1985 (D.c. Law 5-165, D.C. official Code § 8-101 

### et seq.) to revise the SIP.

§110(a)(2)(J) meet the applicable requirements of The District ofColumbia air quality data from the monitoring (Section 127 public notification) section 7421 ofthis title (relating to public notification ) network are published on EPA's AirNow website and the annual summary ofall monitoring data, including exceedances and violations ofstandards, are published onEPA's Air QualityData Mart.

§110(a)(2)(K) provide for: (i) the performance ofsuch air quality modeling as the Administrator may prescribe for the purpose ofpredicting the effect on ambient air quality ofany emissions ofany airpollutant for which the Administratorhas established a national ambient air quality standard, and

(ii) the submission, upon request, of datarelated to such air quality modeling
to the Administrator; (i) The performance ofair quality modeling is a SIP process required to predict the effect on ambient air quality necessary to demonstrate attainment oftheNAAQS. In support ofthe 1997 PM2.5 NAAQS, the District's air quality modeling for PM2.5 was performed as a part ofthe regional SIP planning process through MWAQC. As part offuture PM2.5 SIPs, the District's air quality modeling will beperformed aspart ofthe regional SIP planningprocess through MWAQC orits

successors. (ii) In support ofthe 1997 PM2.5 NAAQS, the PM.25 modelingperformedbyMWAQC was submitted as part ofthe District's PM2.5 SIP submittal on April 4, 2008. Inthe future,

4DC will continue to submit air quality modeling data as part of its PM2.5 SIP submissions developed as part ofthe regional planning process through MWAQC or its successors as required under sub-objective 1.1.1 ofthe District's Section 105 grant. Upon request, DC will submit current and future data relating to such air quality modeling to the Administrator.
